We are a small group, passionate about our involvement in, and development of open-source, educational software to serve the building industry. Our backgrounds range from architecture to 3D modeling. We are bikers, gamers, educators, and readers; we have IKEA-desk team-building exercises and rearrange the furniture at least twice weekly. We are on a quest to try every restaurant surrounding our daylit, naturally vented, historic office in Berkeley, from the hot dog stand at Ashby BART to the less-cost-prohibitive fringes of the Gourmet Ghetto. We LOVE acronyms.
